The Colors of Earth Are Changing
Our world is a colorful place. Just think of the vivid blues, greens, oranges, reds and yellows of Grand Prismatic Spring in Yellowstone National Park, the rainbow-hued mountains of Zhangye National Geopark in China or the shimmering green and purple bands of light in the aurora borealis above the tundra in Churchill, Manitoba, Canada.
